Shohei Ohtani has only 121 PA and does not come close to qualifying. The fewest among the DH qualifiers is 187. The top ten in PA by any batters so far in 2018 all have at least 255.

Ohtani has OPS+ 156. The DH leader in OPS+ J.D. Martinez leads the American League in Home Runs and RBI. This season Martinez has started 29 games as DH and 26 in the outfield. So why not put Martinez in the outfield and let Ohtani DH? The starting outfielders in the American League are likely to be Mike Trout, Aaron Judge and Mookie Betts (currently on 10 day DL). No, Martinez clearly deserves to to be a starting All Star at DH.

91 pitchers have enough innings to qualify for leadership in ERA. The fewest among them is 57 innings. Ohtani has pitched only 45 innings and does not qualify. The most innings is 81.

Ohtani's ERA+ is 130. 23 qualifying pitchers are higher. Here are the tops:

So Ohtani does not come close to deserving to be an All Star as a pitcher.

But the selection by the fans is largely a popularity contest. The Major League encourages fans to vote early and often. It's hardly a serious merit based process. The team manager selects non starters, so should that manager select Ohtani?

If Ohtani is selected, what player would he replace as backup DH? The DH group includes C.J. Cron, Nelson Cruz and Khris Davis, all with comparable OPS+ to Ohtani in way more PA.

So the people who blithely insist that Ohtani must be on the All Star team should step back and think it over.
